ST00016LB-D
A new upper deck aft bulkhead partition replaces the existing aft bulkhead partition. This new partition creates additional floor space that allows the upper deck seats to be relocated, thus providing increased bulkhead space for the first row of seats. The new partition consists of five (5) separate panels which are mounted at floor level on existing seat tracks with standard fittings. The upper portion of the partition is attached using existing structure on the frames and tie rods running to the top of the bulkhead. This modification was accomplished in accordance with United Air Lines DAS-1-WE Approved Master Drawing List No. 00016, dated March 5, 1996, or later FAA approved revisions. Held by United Airlines INC, which holds 520 approved modifications in all. Last revised November 30, 2011. System: cabin, seats and restraints.

What an approved modification is
A supplemental type certificate is the FAA's approval of a change to a certified design: a new engine or propeller, avionics, an autopilot, floats, a parachute, a larger fuel tank, an ice-protection kit. The company holding it may sell the kit and the paperwork to owners of the listed models; the modification then becomes part of that aircraft's record. The FAA's list says what was approved and for which models, not how many aircraft carry it.
